Stacking Capacity: 4 Chairs The all-plastic chair Tip Ton can be tilted forward a few degrees from the normal position. This forward-tilt straightens the pelvis and spine and thus improves circulation to the abdominal and back muscles. Together with Edward Barber and Jay Osgerby, Vitra has now developed a version of the chair that is manufactured from recycled plastic: Tip Ton RE. The high-quality recycling material stems from recycled household waste, particularly used packaging. Utilizing this raw material instead of petroleum-based primary plastics generates 54% less climate-damaging emissions, with a significant reduction in primary energy consumption. To achieve the required stability and quality, the recycling material is mixed with a proportion of glass fibres. The dark grey hue of Tip Ton RE is the natural shade of the processed recycling material, which therefore exhibits very slight irregularities in color Tip Ton RE is itself 100 % recyclable and can be stacked up to four chairs high.
